Jacket



FIG. 1 is a left perspective view of a jacket, showing my new design;

FIG. 2 is a right perspective view thereof; and,

FIG. 3 is a front view thereof.

The regular dot-dash lines are included for the purpose of illustrating portions of the jacket that form no part of the claimed design. The bold dot-dash lines represent boundaries of the claimed design. The contrast of shading/stippling used in various regions represents a difference in appearance either by color, texture, material and/or finish. 

CLAIM I claim the ornamental design for a jacket, as shown and described.
